To all whom 2'2? may concern Be it known that I, ARTHUR A. OLLEN- BERG, a citizen of the United. States, residing at Milwaukee, in the county of Milwaukee 5 and State of Wisconsin, have invented certain new and useful Improvements in Bumper-Brackets for Automobiles, of which the following'is a specification, reference being had to'the accompanying drawing, forming a partthereof.

The main objects of this invention are to facilitate the assemblage and separation of the relatively movable parts of the bracket; to avoid unnecessary parts or fastenings which are liable to become loose and rattle,

or detached and lost; and generally to simplify and improve the construction and in crease the convenience of this class of devices.

1 2e It consists in the construction, arrangement and combination of parts, as hereinafter particularly described and pointed out in the claims.

In the accompanying drawing like charactors designate the same parts in theseveral' figures.

Figure 1 is an inside elevation of a bumper bracket embodying the invention in connection with one of various means for attach- 3th ing the bracket to a car and one of various forms of bars which may be used with the bracket; Fig. 2 is a vertical longitudinal section of the bracket on an enlarged scale; and

Figs. 3 and 4c are vertical cross-sections on the lines 3, 3, and at, 4:, respectively, Fig. 2.

A hracket constructed in accordance with the invention comprises two main members, a spring hnrrel housing a, and a stem 2) guided and movable axially therein and proso vided with means for attaching it to a bar 0. Theharrel or housing a; may be attached to any convenient of the frame or to a spring of an automobile in various ways.

As shown in Fig. 1, it is formed with a jaw a, which is pivotally and adj'ustably connected in a well known manner by a bolt (not shown) with a corresponding jaw on a coupling member 6, fastened to a side bar 7 of the frame by clips 9.

This connection of the bracket with the frame provides for vertical adjustment of the bar a, but the housing a may be directly and rigidly attached to the frame or a part of the automobile;

5-5 The barrel or lidusing a is formed at'the bumper bracket are front end with an inturned notched flange I h, as shown in Figs. 2 and 4, and at a distance to the rear of said flange with an internal spring seat, 2', as shown in Figs. 2 and 3.

The stem Z) adjacent to its rear end is freely fitted and guided in the opening in the spring seat i, and at its front end, which projects from the housing, has an enlarged shank j, freely fitting and guided in a larger opening in the flanged end of the housing. This shank at its junction with the smallerpart of the stem 1) forms a shoulder or spring seat and is provided with outwardly projecting lugs Z, which are arranged to reg- 7o ister with and pass through the notches m in the flange h when one part of the bracket is turned around its longitudinal axis into abnormal position relative to the other part.

A spiral spring a, which is made to pass freely through the opening in the flanged front end of the housing a, is inserted with the stem 6 therein and bears, when the parts are assembled as shown in Figs. 1 and 2, at

its rear end against the seat 2' in the housing 0 and at its front end against the seat is on the stem.

By turning one part of the bracket relatively to the other till the lugs Z are out of register with the notches m and engage with the inner side of the flange h, the housing a and the stem 7), when attached to the frame or a part of an automobile and to a bar 0, are locked and held together in the proper working position relative to each other. no

The spring a being more or less compressed when the parts are thus assembled takes up all play or lost motion, prevents rattling and wear, and at the same time per. n its the bar 0 to yield rearwardly in case it, hits or is hit by an obstruction or other body.

. The front end of the stem 6 is formed or provided with a head or connection of ap- )IOPl'lttQ design for attachment to a bumper ar of any desired shape. In the present 104 instance it is formed with a sleeve or collar 0, which is provided with a set screw p for fastening it to and adjusting it lengthwise of a round or cylindrical bar 0, as shown in' Fig. 1..

With the construction herein shown and described, the relatively movable parts of. a

easily and quickly assembled and taken apart, and, when assembled and applied to an automobile, are in- 110 terlocked'and securely held together without bolts, nuts, screws, or other separate fastenings which are liable to get loose and rattle or detached and lost. The bumper spring a is also completely inclosed, concealed and protected.

Various changes in the details ofconstruotion of the device may be made Without denotch in said flange when one of the parts is turned on its axis into abnormal position relative to the other, and a spring bearing at one end against the seat in the housing and at the other end against the seat on the stem and adjacent to the point of engagement of the lug on the stem with the flange 'at theouter end of the housing.

2. A bumper bracket comprising a spring housing provided with means for attachment to a car and having an inturned notched flange at one end and an internal spring seat at a distance from the flange, the opening in the flanged end of the housing being larger than the opening in the spring seat, a stem guided and movable axially in'the openings in the spring seat and flangedend of the housing and having an enlarged shank forming a spring seat and provided with means for attachment to a bumper bar and with a lug which is arranged to register with the notch in said flange when one of the parts is turned relatively to the other into abnormal position, and a spring bearing at one end against. the seat in the housing and at the other end against the seat on the stem adjacent to the point of engagement of the lug on the stem with the flange at the outer end of the housing and adapted to pass through the opening in the flanged end of the housing. i;

In witness whereof I hereto aflix my signature in the presence of two witnesses.
